Abstract

A filter for a fresh air input for a car has the filter (3) mounted under the engine cover so that it is heated by the engine. The heated air prevents damage to the filter material through damp and cold, as well as providing a longer filter life. The filter is in a disposable pack and processes the air to remove fumes and dust. The fresh air inlet has a scoop (4) over the engine cover and the flow is such that only a small heating effect is obtained. This allows the system to be used in summer.

Description

Beschreibung und Erläuterung zur Zusatzpatent-Description and explanation of the additional patent

und -Hilfsgebrauchsmusteranmeldung 'Filter für die Frischluftzufuhr zu Autokabinen mit selbsttätiger Regenerierung gegen Feuchtigkeit' Kraftfahrzeuge werden bei den verschiedensten Wetterperioden benutzt.and utility model registration 'Filters for the fresh air supply to car cabins with automatic regeneration against moisture 'motor vehicles are used in a wide variety of weather periods.

Sonniges, regnerisches, nebliges und Winterwetter mit Frost beeinflussen die angesaugten Luftmengen durch Feuchtigkeitsaufladung sehr stark.Affect sunny, rainy, foggy and winter weather with frost the amount of air sucked in is very strong due to moisture build-up.

Die Ohemisorptionsmassen sind unterschiedlich empfindlich gegen Feuchtigkeitsaufnahme, insbesondere der CO-Katalysator ist sehr stark feuchtigkeits-empfindlich, so daß schon bei geringer Feuchtigkeitsaufnahme die Chemisorption sehr stark nachläßt.The Ohemisorptionsmassen are differently sensitive to moisture absorption, in particular the CO catalyst is very sensitive to moisture, so that the chemisorption decreases very strongly even with low moisture absorption.

Um die Nachteile der Feuchtigkeitsaufnahme fast gänzlich auszuschalten, wird erfindungsgemäß vorgeschlagen, das Gehäuse des Chemisorptionsfilters in den natürlichen Abwärmebereich des Motors in gekapselter Form einzubringen.In order to almost completely eliminate the disadvantages of moisture absorption, is proposed according to the invention, the housing of the chemisorption filter in the to bring in the natural waste heat area of the engine in an encapsulated form.

Durch diese erfindungsgemäße Maßnahme wird erzielt, daß 1. die angesaugte Luft sich um ca. - je nach Auslegung - 1 bis mehrere Grade erwärmen kann und dadurch keine Feuchtigkeitsabgabe an die Chemisorptionsmassen erfolgt, so daß durch diese erfindungsgemäße Maßnahme die Chemisorption durch Luftfeuchtigkeit nicht beeinträchtigt wird.By this measure according to the invention it is achieved that 1. the sucked Air can heat up by approx. - depending on the design - 1 to several degrees and thereby there is no release of moisture to the chemisorption masses, so that this Measure according to the invention, the chemisorption is not impaired by humidity will.

2. Nach Stillsetzen des Motors ist die Abstrahlung so groß, daß das Filtergehäuse durch die Abstrahlungswärme und somit auch die Chemisorptionsmassen einem stetig sich wiederholenden GrocknungsprozeB unterliegen und regenerieren, wodurch die Chemisorptionsmassen bei j zudem Neubeginn der Autofahrt wieder vollkommen trocken und aktiv sind.2. After the motor has stopped, the radiation is so great that the Filter housing through the radiated heat and thus also the chemisorption masses are subject to a constantly repeating grouting process and regenerate, whereby the chemisorption masses are also completely restored when the car journey starts again are dry and active.

Durch diese erfindungsgemäße Maßnahme wird jegliche Fremdenergiezunahme durch Heizspirale oder Fremdheizvorrichtungen, die zusätzlich Energie benötigen bzw.This measure according to the invention eliminates any increase in external energy by heating coils or external heating devices that require additional energy respectively.

Motorleistungen verringern würden und somit global Kosten verursachen würden, vermieden.Would reduce engine performance and thus cause global costs would be avoided.

Trotzdem wird durch natürliche Aufwärmung, um die geeignete Maßnahme der gekapselten Filtervorrichtung im Abstrahlungsbereich des Motors zu erstellen, die Standzeit des Chemisorptionsfilters um ein Mehrfaches heraufgesetzt und somit erst wirtschaftlich machbar gestaltet.Even so, through natural warming up, the appropriate measure to create the encapsulated filter device in the emission area of the engine, the service life of the chemisorption filter is increased several times and thus first made economically feasible.

In der beiliegenden Zeichnung ist dargestellt: mit 1 ein Personenkraftwagen, mit 2 der Motorraum, mit 3 ein gekapselter Filter, mit 4 die Frischluftzufuhr, mit 5 die Personenkabinenluftzufuhr der gereinigten Luft, die durch den von außen aufgeheizten Filter geführt wird.The accompanying drawing shows: with 1 a passenger car, with 2 the engine compartment, with 3 an encapsulated filter, with 4 the fresh air supply, with 5 the person cabin air supply of the purified air, which is heated by the externally Filter is performed.

Die Luftaufwärmung an heißen Sommertagen um z.B.The warming up of the air on hot summer days by e.g.

1 - 20C ist unerheblich, die Luftaufheizung in den Wintermonaten im Fahrzeuginnern sogar gewünscht.1 - 20C is irrelevant, the air heating in the winter months in Vehicle interior even desired.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, im Strahlungsbereich der Motorabwärme gekapselte, nicht durch Motorgeruch oder Abgase beeinflußte Filtermedien einzubringen, die schichtweise je nach Verbrauch auswechselbar sind und außerhalb der Motorhaube Frischluft zugeführt bekommen, diese etwas aufheizen und sie somit mit relativ geringerer spezifischen Feuchte durch die Chemisorptionsmassen durchfließen, um den Personen in der Kabine als gereinigte Atemluft zu dienen.Of course, the invention is not limited to the above in detail The forms of training described are limited, but there are numerous changes possible, without deviating from the basic idea, in the radiation range of Engine heat encapsulated, not influenced by engine odor or exhaust fumes Bring in filter media, which can be exchanged in layers depending on consumption and get fresh air outside the bonnet, heat it up a little and they therefore have a relatively lower specific humidity due to the chemisorption masses flow through to serve as purified breathing air for the people in the cabin.
